I'm reloading for my .300 WSM using H380 behind 165 grain noslers.
I originally seated all my loads to the max OAL which is 3.860" and when I went to chamber a round it was contacting the lands so I bought a Hornady OAL gauge to get the proper seating depth.
I did it several times and came to an average of 2.917". I was under the impression that for accuracy you want your bullet to be approx .001" off the lands. Im confused since even if I back off the recommended .001" the round is still over the max OAL.
I also measured several factory rounds and got an average of 2.747" OAL.
Is there something I am doing wrong or not understanding correctly?
